This is provided to achieve capability of avoiding hindrance of accurate reflection of intention at the time of production due to execution of frame interpolation on the reception side. A predetermined container including a video stream obtained by performing encoding operation on moving image data of a predetermined frame rate is transmitted. Information for restricting frame interpolation is inserted into one or both of a layer of the container and a layer of the video stream. For example, the information for restricting frame interpolation includes information for prohibiting frame interpolation. Moreover, for example, the information for restricting frame interpolation includes information indicating the number of times of frame repeats.

Systems and methods are described adjusting a media asset consumption environment based on detected changes in status of an object. For example, a media guidance application may detect a change in setting of a device in a first room and, in response to detecting the change in the setting, may determine the state of an object in the room. Based on the detected change in the setting and of the state of the object, the media guidance application may identify a setting for a media consumption device and may modify setting of the media consumption device so that it is consistent with the conditions defined by the change in the setting and the state of the object.

Methods, systems, and media for synchronizing audio and video content on multiple media devices are provided. In some embodiments, the method comprises: receiving, at a media device, an indication of a media content item to be presented using the media device, wherein the media device includes an audio component for presenting audio content associated with the media content item and a video component for presenting video content associated with the media content item; determining that the media device is associated with a group of media devices for presenting the media content item, wherein the group of media devices includes the media device and at least one audio device that presents the audio content associated with the media content item; generating an audio timestamp that controls the presentation of the audio content on the group of media devices; generating a video timestamp that control the presentation of the video content on the group of media devices, wherein the video timestamp is based on the generated audio timestamp; and causing, at the media device, the video content associated with the media content item to be presented using the generated video timestamp and causing the audio content associated with the media content item to be simultaneously presented by the at least one audio device in the group of media devices by transmitting the audio timestamp to the at least one audio device in the group of media devices.

A reception side can easily recognize that metadata is inserted into an audio stream. A container of a predetermined format including an audio stream into which metadata is inserted is transmitted. Identification information indicating that the metadata is inserted into the audio stream is inserted into a layer of the container. At the reception side, it is possible to easily recognize that the metadata is inserted into the audio stream and acquire the metadata reliably without waste by performing the process of extracting the metadata inserted into the audio stream based on the recognition.

Convenience in a decoding process on a receiver side for when a predetermined number of high-quality-format image data is transmitted together with basic-format image data is achieved. A base stream including, as an access unit, encoded image data for each picture of basic-format image data, and a predetermined number of enhanced streams, each including, as an access unit, encoded image data for each picture of high-quality-format image data are generated. Here, a predictive coding process is performed on image data in high-quality format by referring to the image data in basic format or image data in another high-quality format, by which an enhanced stream is generated. Then, information indicating decoding order is added to each access unit of the enhanced streams. A container in a predetermined format that includes the base stream and the predetermined number of enhanced streams is transmitted.
